[Solved] One folder per email address, in the "Folders" view

Hello, I have used Thunderbird for many years. Currently, I am using version 102.12.0 (64 bit) and my OS is KDEneon 5.27 I have multiple email addresses (using IMAP or POP) which are filed under "Local Folders" ("Dossiers locaux" in french) A) In the "Folders" view, I would like to be able to have one folder per email address. B) And, similarly, I would like that for: "Account Settings" -> [e-mail] -> "Copies & Folders" : 1)  "When sending messages, automatically:" -> "Place a copy in:" -> " "Sent" Folder on:" 2) -> "Message Archives" -> "Keep message archives in:" -> " "Archives" Folder on:" 3) -> "Drafts and Templates" -> "Keep draft message archives in:" -> " "Drafts" Folder on:" 4) -> "Drafts and Templates" -> "Keep message templates archives in:" -> " "Templates" Folder on:" get a folder named after the email address, not in "Local Folders" as is currently the case. I did see the following help articles: [[https://support.mozilla.org/en-US/kb/faq-changing-imap-pop|faq-changing-imap-pop]] [[https://support.mozilla.org/en-US/kb/switch-pop-imap-account|Switch-pop-imap-account]] But that's not what I want. If I have an email address using the POP protocol, I want to keep it in POP, but having its own folder in the "Folders" view In the same vein, if I have an email address using the IMAP protocol, I want to keep it in IMAP, but having its own folder in the "Folders" view. Anyway, for my addresses using the POP protocol, I often have many more emails than my supplier agrees to store on his server. In short, if you have a solution, it will be great. Thank you in advance. Good day to you all.
